APT Announces Agreement with Cree Inc. for Purchase of Silicon Carbide ''SiC'' Schottky Diode Die.Business Editors BEND, Ore.--(BUSINESS WIRE)--Aug. 5, 2003 Advanced Power Technology (Nasdaq:APTI APTI Association for Preservation Technology International APTI Air Pollution Training Institute ) is pleased to announce that it has reached an agreement with Cree Inc., for purchase of SiC ZERO RECOVERY(TM) Schottky Diode The Schottky diode (named after German physicist Walter H. Schottky; also known as hot carrier diode) is a semiconductor diode with a low forward voltage drop and a very fast switching action. die for packaging and selling of finish products under the APT brand name. APT intends to primarily address market segments not currently served by Cree, mainly using alternative packaging and innovative engineering. APT will use its expertise in high power semiconductor manufacturing to offer multi-die parallel discrete devices in TO-220, TO-247, D2, D3, and SOT-227 packages as well as hermetic hermetic /her·met·ic/ (her-met´ik) impervious to air. her·met·ic or her·met·i·cal adj. Completely sealed, especially against the escape or entry of air. packages with and without military screening. In addition, APT will offer the latest generations of MOSFETs and IGBTs built in combination with the SiC ZERO RECOVERY(TM) Schottky diodes in both boost and buck configurations. Power Modules and other custom designs using the SiC ZERO RECOVERY(TM) Schottky diodes will also be offered. Key Features -- Faster switching speed compared to silicon diodes, up to 500 kHz, allowing smaller EMI (ElectroMagnetic Interference) An electrical disturbance in a system due to natural phenomena, low-frequency waves from electromechanical devices or high-frequency waves (RFI) from chips and other electronic devices. Allowable limits are governed by the FCC. filter and other passives -- Switching losses nearly eliminated resulting in 3%-7% reduction in PFC PFC abbr. private first class Noun 1. PFC - a powerful greenhouse gas emitted during the production of aluminum perfluorocarbon power consumption -- High thermal conductivity resulting in lower operating temperature enabling smaller heat sink A material that absorbs heat. Typically made of aluminum, heat sinks are widely used in amplifiers and other electronic devices that build up heat. Small heat sinks are the most economical method for cooling microprocessors and other chips. to be used for compact designs -- Rated at 175 degrees C for higher temperature operation or enhanced reliability at lower temperatures -- Extremely low leakage at elevated temperature due to higher band gap -- Easy paralleling due to negative temperature coefficient A negative temperature coefficient (NTC) occurs when the thermal conductivity of a material rises with increasing temperature, typically in a defined temperature range. For most materials, the thermal conductivity will decrease with increasing temperature. -- 600V to 1200V breakdown available -- Power Modules and custom products available Availability and Pricing Product samples in a wide range of current ratings, breakdown, and packages. Limited samples are available now with high volume production available in 4Q2003. Contact factory for additional product information and pricing.
